In this case, it becomes important to resolve the system issues caused by missing or corrupt drivers, Windows registry entries that have become corrupted, or system not being able to read HDD external hard drives. Hard drive data recovery is not an easy task. An easy way to make the disk space usable again is to format it and then reboot the computer. Doing this would delete all existing data. You can further reinstall the setup wizard either from Windows boot disk or download the class specific driver required. You will lose all the media and files that you have been saved on this disk drive, and there is no way to recover disk space once it has been overwritten.
Unless you are dealing with a completely dead media storage that has experienced a hardware failure, there are ways to restore some of the material that was stored on your drive. What do you do when you accidentally hard-delete a file and need to restore it? Download and install data recovery software or ask for online technical support to restore from backup. For this you need to have a backup system set on your computer that saves file changes on a regular basis. Windows 7 has an in-built disk partitioning utility that can help Windows users utilize different portions of their drive without running the risk of crashed hard disk. Without a Windows backup, a corrupt disk would require you to reinstall Windows and lose all previous settings.
